I drive a total of 60 miles a day to work and back home. I travel both on highway and city. I use the ECO feature when dealing with traffic and have on the average (depending on where I buy my gas) get 34mpg. I have noticed with lower grade stations, the perfomance is less. The pickup while using ECO is a bit regulated but with a quick click, you can turn it off and get the punch you need to pull quickly ahead.
I replaced this car with a 2007 PT Cruiser which had horrible gas milage. I find the instrument panel great with the RIO SX model and love the rear screen view due to the limited viewing of the rear window.
I would definitely recommend the Rio to other buyers. It is fun to drive!
Instrument panel w/mpg values and number of miles before you are out of gas. Interior is sporty and sleek.
